There have been a lot of commotion operations in history.

For example, saltpeter for making gunpowder.

The saltpeter used by millions of armies must have been mined from mines, right?

Wrong!

It's a toilet!

Basically, most saltpeter is scraped from the white powder in toilets, pigsties, and house walls.

Countless histories have shown that the agricultural and military roles contained in the toilet are really extraordinary.

Why does the septic tank explode, why the white ash in the corner of the wall is used as military supplies, why the urine pool in the toilet can be scraped and purified to obtain potassium nitrate, this is all science!

The people of Heishui County don't buy any arms, they do it themselves.

Iron or something to smelt by yourself, as for gunpowder...... People in Zhuangzi village collect a large amount of urine from village women to extract potassium nitrate.

There are really a lot of chemical talents in Heishui County, especially in military knowledge, which has been passed down from generation to generation.

Not only in this era, but also at home and abroad in another world, such as the American Civil War, the wars in modern Europe, and the difficult times of the domestic army, this kind of soil method in the toilet was basically used to make gunpowder.

That is, in peacetime, Wang Lanling's plan to go to the countryside will be allowed.

In times of battle, the toilet is the guarantee of productivity and combat effectiveness!

The previous regulation was to strictly control the toilets in each house, not only to strengthen the control capacity, but also to restrain the dangerous behavior of some people.

But Lord Xiao Wang is stupid, he doesn't know anything, and he dares to change the rules for a little money.

Yun Tiantian didn't want to take care of the matter, so he threw the problem to his superiors, and Jiang Xinzhi decisively denied it, and also handed over this document, hoping that the emperor and the officials of Dragon City would know how ignorant this kid was and not reuse him.

[Jiang Xinzhi: The minister thinks that this law is impossible! ] Giving the rights of the yamen to the small people, for fear of causing trouble, Heishui children are ignorant and ignorant, and it is not recommended to reuse it. 】

However, the old emperor agreed......

This is really not to blame Yun Tiancai, his idea is that there will definitely be a smart person who will stand up in the end.

Jiang Xinzhi stood up against it, and handed it over, clearly indicating his attitude, hoping that everyone would join him in opposing this ignorant child.

The officials in Longcheng can basically see the problem clearly, but Wang Lanling's original plan to go to the countryside is too circuitous.

Everyone else understands it, but the old emperor doesn't understand it!

After the old emperor agreed, the rest of the people really stepped on the horse with bitter words, like a fish in the throat.

Fortunately, this big dung plan to go to the countryside is only tossed in Heishui County, although I am not happy, but I also endure the disgust and ignore it, anyway, there is no trick in the land of projectiles.

After studying for three years, Wang Lanling realized how lucky he was, and he felt even more that the water in Dragon City was deep and unfathomable!

It is no longer possible to guess the logic with reason and brain.

Wang Lanling's manufacture of public toilets cannot meet the needs of the moment, so the establishment of the dung division is imperative!

Iron ore and copper ore, these two have been obtained, and Wang Lanling began to prepare after returning to the county.

As for what to replace the sulfur in the three formulas of gunpowder except saltpeter charcoal, the talents in Heishui County have already invented the soil method.

Wang Lanling called Gong Yueman, "I have obtained permission from the county guard to use the iron and copper mines in the nearby mountains, and sugar cane cannot be grown here because of the climate, you have to think of a way to come up with a substitute for sulfur." ”

Gong Yueman said happily: "This is easy to do, how did the lord persuade the county guard to give us important materials such as iron ore and copper ore?" ”

The problem of gunpowder is not a problem, Gong Yueman is more curious about how Wang Lanling persuaded the county guard, you must know that this kind of thing is a bit unruly.

"Know it with affection, move it with courtesy." Wang Lanling said eight words simply, and then changed the topic, "How is it, are those horse thieves here?" ”

Wang Lanling has been going back and forth for a week, and I feel that there has not been much change in the county.

Gong Yueman said: "Not for the time being, these days the squires and officials in the city are mobilizing the people to build the city wall, and they haven't found enough people for a few days, not to mention things such as wood and stones, and the basic iron tools and tools have not been found." ”

Wang Lanling also knew how poor this county was, and said helplessly: "Even if it is mining, you need metal tools, it's really hard, let's open an iron-making factory in the city first, and find some iron ore from the mining area to make tools." ”

Gong Yueman promised: "Yes, as long as you can use the things in the iron ore, things will be easier in the future." ”

Wang Lanling said: "Then the matter here will be handed over to you first, I estimate that the people of Heishui County should also enter the scope of Muzhou, it will take more than a month from Yanshan Lake to Heishui County, and it has been a month since I entered Muzhou, and now I am really a little worried, Hu Zhong and I will take five people out, and you are presiding here." ”

"Yes!" Gong Yueman said cautiously: "It's better to bring more people, I'm worried that I will encounter horse thieves on the road, and now your safety is more important than the 100,000 people in this county." ”

Wang Lanling smiled, "There are not so many, and there are not too many people, Hu Zhong and I called the people of the Iron Camel Tribe on the road, Hu Wangxiang should also move, and when the three parties converge, it will be a team of 1,000 people." ”

Gong Yueman saw that Wang Lanling had a plan, so he didn't say much, and soon talked to Wang Lanling about other things.

"In the past few days, people in the city have said that they will not be able to go up to the mountain to pick mushrooms in a few days, so while they can still find mushrooms, they all go to the mountains to find mushrooms in large groups.

Wang Lanling smiled, "Isn't this a matter of clarity?" If you are poisoned, you will be poisoned, and if you die, you will die, and although I have the obligation to educate all peoples, some people are also free. ”

Gong Yueman said: "I think even if these people eat mushrooms and die, they can't serve as a warning to others, I've been here for more than a year, because there are many people who have died from poisonous mushrooms, and the rest of them just don't take it seriously, it's useless to say anything." ”

Wang Lanling shook his head, "It's not useless, it's useless to some people." This kind of thing doesn't happen to them, it's not their own son who is poisoned, they won't care. ”

"You only see those who don't listen to persuasion, those who don't eat mushrooms because the people around them eat mushrooms and are poisoned, and they won't jump out and tell you this."

Gong Yueman felt a lot better, "In this way, the adults still understand." ”

Wang Lanling said: "Some people don't listen to persuasion now, I will prohibit the villagers from going up the mountain in a few days, as for the mushroom thing, when the time comes, build a mushroom house dedicated to growing mushrooms, you can grow vegetables and beans, why not specialize in mushrooms?" ”

Gong Yueman thought for a while and said: "The gains outweigh the losses, mushrooms are all over the mountains, and they don't need to be taken care of, and it doesn't take much effort to get them, and most people won't specialize in growing this." ”

Wang Lanling said indifferently: "Anyway, some people are idle, and they are supported when they are full, and it is good to use some manpower to improve their diet." ”

Gong Yueman felt that this was okay, just like Wang Lanling said, they have a lot to do now, and when they have time, it is not difficult to give a mushroom house to the people in the city who like to eat mushrooms.

Of course, even if some people like to eat ordinary mushrooms, they love to eat wild mushrooms to challenge the 50% chance of life or death, and they want to eat flower mushrooms.

This kind of is really looking for death.
